Description

Technical Field

[0001] The utility model relates to a laboratory appliance, in particular to an automatic capping machine for a sample injection bottle. Background Art

[0002] In the field of analytical testing, sample bottles are usually used to temporarily store liquid samples to be analyzed, such as serum, plasma, urine, saliva, cerebrospinal fluid, tears, digestive fluid, etc. After placing the above liquid samples in the sample bottle, a lid is needed to seal the open end of the sample bottle to prevent the liquid sample in the bottle from spilling during transportation.

[0003] However, when the number of injection bottles is too large, it takes a lot of time to manually screw or snap the caps into the openings of the injection bottles, resulting in very low experimental efficiency.

[0004] Patent No.: "CN208135852U" discloses a sample injection bottle capping device, including a sample injection bottle, a fixing frame for fixing the sample injection bottle, and a capping operation table; the capping operation table includes a lower support plate, an upper support plate, a supporting fixing column fixedly connecting the lower support plate and the upper support plate, a pressing handle and a sliding rod, and a gap for accommodating the fixing frame is formed between the lower support plate and the upper support plate; a through hole is provided at a position corresponding to the upper support plate and the sample injection bottle, and accordingly, a columnar protrusion for pressing the bottle cap is provided on one side corresponding to the pressing handle and the upper support plate, and the columnar protrusion is adapted to the through hole; the sliding rod is slidably arranged on the upper end surface of the upper support plate, and the pressing handle is provided with a sliding hole adapted to the diameter of the sliding rod, and the pressing handle is slidably connected to the sliding rod. However, the above scheme still requires manual pressing of the pressing handle to press the bottle cap into the sampling bottle. However, in this process, it is impossible to manually ensure that the pressing force is maintained within a safe range each time. Once the pressing force is too large, the sampling bottle will be at risk of breaking, and the liquid sample in the bottle will flow out. Resampling is particularly cumbersome or even impossible. Therefore, there is an urgent need for an automatic capping machine that can maintain the same pressing force. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to solve the problems in the prior art of low manual capping efficiency, uneven capping quality, and easy damage to sample injection bottles.

[0006] The technical solution of the utility model is:

[0007] An automatic capping machine for sample injection bottles includes a machine body, a motor is arranged inside the machine body, a capping plate is arranged at one end of the machine body away from the motor, a screw shaft is connected to the output shaft of the motor, the end of the screw shaft away from the motor is rotatably connected to the capping plate, and the screw shaft is perpendicular to the plate surface of the capping plate, a screw nut is arranged on the screw shaft, a loading platform is fixedly arranged on the periphery of the screw nut, and a plurality of loading holes for loading sample injection bottles are arranged on the side of the loading platform close to the capping plate. The motor can drive the screw nut and the loading platform to move along the screw shaft toward the capping plate, so that a plurality of sample injection bottles with caps placed thereon, which are located on the loading platform, can simultaneously press the caps of a plurality of sample injection bottles under the pressure of the capping plate and the loading platform, thereby greatly enhancing the work efficiency and reducing the labor intensity.

[0008] Preferably, a control button is provided on the fuselage, a control circuit board is provided in the fuselage, and the control button is electrically connected to the motor via the control circuit board. An operator can control the motor by operating the control button.

[0011] Preferably, a sliding rod is further provided in the fuselage, and a sliding hole for the sliding rod to pass through is provided on the loading platform, and the axis of the sliding rod is parallel to the axis of the screw shaft.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] The utility model is an automated device which can simultaneously perform the operation of pressing the bottle caps of a plurality of sample injection bottles, thereby greatly improving the work efficiency and reducing the work intensity.

[0014] By using the sample injection bottle with the bottle cap pressed by the utility model, the degree to which the bottle cap is pressed into the sample injection bottle is uniform, thereby greatly improving the work quality.

[0025] Furthermore, in order to prevent friction and wear between the coupling 14 and the motor 3 and / or the body 1 , a thrust bearing is provided between the coupling 14 and the motor 3 .

[0026] Specifically, a photoelectric sensor 15 is provided on the loading platform 6 , and a positioning pin 16 is provided on the body 1 . The photoelectric sensor 15 determines the zero position (the position when loading and taking out the sample injection bottle 8 ) by identifying the positioning pin 16 .

[0027] Specifically, a control button 10 is disposed on the body 1 , a control circuit board is disposed inside the body 1 , and the control button 10 is electrically connected to the motor 3 via the control circuit board.

[0028] Specifically, the control button 10 includes:

[0030] First mode button 12:

[0031] 1. Moisture induction: Motor 3 pushes the sample bottle at a speed of 4r / s to a height of 1 (motor 3 runs 7.7 circles) and then stands for 8 seconds;

[0032] 2. Capping: Motor 3 pushes the sample bottle at a speed of 0.2r / s to a height of 2 (motor 3 runs 1.5 circles) and then stands for 4 seconds;

[0041] Working process and principle:

[0042] During normal operation, the staff only needs to simply place the bottle cap 9 in the sample injection bottle 8, and then insert the multiple sample injection bottles 8 with the bottle caps 9 simply placed into the loading holes 7 of the loading platform 6 as a whole, and then press the control button 10 to start the motor 3. The motor 3 drives the screw shaft 4 to rotate, and the screw nut 5 drives the loading platform 6 to move along the screw shaft 4 toward the pressure cover plate 2. The bottle caps 9 of multiple sample injection bottles 8 can be pressed together at the same time by relying on the pressure cover plate 2. Then, according to the preset program, the motor 3 reverses, and the screw nut 5 drives the loading platform 6 to move along the screw shaft 4 away from the pressure cover plate 2. When the photoelectric sensor 15 on the loading platform 6 recognizes the positioning pin 16 on the body, it is confirmed that the loading platform has returned to the zero position, which is convenient for the staff to take the sample injection bottle 8.
